Symmetric Few-Mode Fiber Couplers as the Key Component for Broadband Mode Multiplexing

Autor: Dimitris Syvridis, C. P. Tsekrekos

Publikováno v: Journal of Lightwave Technology. 32:2461-2467

All-fiber broadband mode multiplexers (MMUXs) for mode and wavelength division multiplexing transmission systems are designed and analyzed. The MMUXs are based on cascaded 2-D or 3-D symmetric few-mode fiber (FMF) couplers. The MMUXs are optimized fo

Scaling multimode fibre IM/DD transmission capacity through spatial-spectral multiplexing

Autor: D. I. Kassos, Stylianos Sygletos, Dimitrios Syvridis, N. G. Varithimiadis, C. P. Tsekrekos

Data centre connections can greatly benefit from parallel transmission channels on one multimode fibre (MMF). Shortwave wavelength division multiplexing (SWDM) achieves parallel transmission through spectral multiplexing. Furthermore, MMFs offer a sp
